EDWARD BECKER, CF TEMORA, NEW SOUTH XVALES.

SHEEP-SHEARING MACHINE;

SPECIFICATION forming part of Letters Patent No. 650,071, dated May 22, 1900.

have invented certain new and useful Im provements in Sheep-Shearin g Machines; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

- This invention relates to improvements in sheep-shearing machines and the operating mechanism therefor.

The objects of this invention are, first, to provide a machine the friction and vibration of whose working parts are each reduced to a minimum; second, to substitute a slow scissors cutting movement for the high-speed chewing movement which has heretofore been a universal defect in all sheep-shearing machines, and, third, to provide an improved tension-gear and an easy method of removing and replacing the blades.

In the accompanying drawings, Figure 1 is a view in perspective of the cutting-head. Fig. 2 is a similar view with parts removed. Fig. 3 is a plan view of the reciprocating cutter. Fig. 4 is a similar view illustrating the upper face of the body of the cutting-head. Fig. 5 is a plan View of the lower section thereof with cutting mechanism in operative position. Fig. 6 is a bottom plan view of the upper section of the cutting-head. Fig. 7 is a top plan view thereof. Fig. 8 is a detail view of the reciprocating lever. Figs. 9, 10, 11, 12, 13, and 14 are detail views of the tension appliance. Fig. 15 is a detail. Fig. 16 is a detail view of the drive-pinion and its flexible shafting. the cutter-head.

Referring to the drawings, A is the lower cutting-blade.

B is the oscillating cutting-blade.

O is the lower section of the body of the machine, to which the blade A is secured.

D is the oscillating plate, to which is attached upper blade B.

E is an upper section ofbody of machine.

0 is top of fixed pillar connecting the upper and lower sections of the body of the ma- I chine.

Fig. 17 is a plan view of Serial No. 722,096. (No model.)

. gear-wheel revolves,as hereinafter described.

H is the handle of machine. J is a covering of flexible shaft. 7

A is a spring attachment which consists of a light steel spring, as shown, having a cone shaped head A fitting into a suitable recess in blade A and secured by a screw A The blade A is held rigidly in position by the raised sides 0 C of the body.

A A are lubricating-oil reservoirs.

The fixed pillar O is secured to the inner face of the lower section of body 0, over which the upper body E fits and to which it is secured by means of the nut 0 Fig. 1.

C is an adjustable collar screwed to the pillar, as shown, provided for the purpose of forming a connection which will not work loose by reason of vibration. The upper face of this collar is cupped to correspond to a raised cone-shaped ring or fixed washer E surrounding the aperture E in the upper section of body E, Fig. 6, through which the pillar passes, so that when the nut 0 Fig. 1, is screwed tight the said ring or washer E is securely embedded in the cupped recess of the collar 0 thus forming a rigid and locked joint.

0 isa fixed .pivot on which the plate D, carrying the cutting-blade B, oscillates.

D D are studs fixed in plate D, securing the blade 13 thereto. These studs are made so that the blade can be lifted off and replaced at will.

D is an aperture in plate D, through which pillar 0 passes. (See Fig. 5.)

D is an aperture to receive thumb of re-' ciprocating lever by which plate D is oscillated.

D is an aperture to receive pivot 0 E is an aperture through which pillar 0 passes.

E is an aperture through which tension screw passes.

F. is an opening partially covered by plate E, to which is attached spindle K, on which the reciprocating lever L rotates.

.body E.

K is a tapped hole in spindle K, into which screw K Fig.1, fits.

E E are screws securing the plate F. to

E E are screw holes through which passthe screws securing the mechanical chamber G to the body of machine. Fig. 4, shows the position taken up by the mechanical chamber G. As will beseen from the drawings, particproject beyond those of the upper blade B, and thus prevent the oscillating blade from coining into cutting contact with the pelt of the sheep. By this means the need for a comb is obviated. v

The spring (1 is provided for the purpose of. facilitating theremoval and replacing of the blade B by holding the oscillating plate Din positiom v The reciprocating lever L is mounted on spindle K and is provided with a slot. U, by means of which the rotary motion of the revolvin'g shaftis changed into an intermit ten-t: oscillating movement, which in turn is transmitted to the plate D by means of the thumb L, as shown in Fig. 6.

L L are the apertures through which the spindle K passes, on which the reciprocating lever oscillates. The transmitttn g thumb L consists of a detachable angle-piece, the upw perportion of which fits into a recess in one end of the. lever, as shown, and is secured therein by means. of pivot L The recess is so constructed as to allow the thumb L a certain amount of play to enable it to accommodatfeitselfto the difierences in radius between the reciprocating lever and the oscillating plate, a; small spiral spring L being provided forithe purpose, of retaining the thumb Lin its'normal position.

F'isa bent. shaft mounted in bearings F F and to which is pivoted a tension-block F ,'retained in position by a spring F At one end of shaft F and at right angles thereto is formed a pair of jaws F F between which the tension-screw is secured by means of a pin F Said screw is formed in two parts or members. F F, the member F being provided'with a longitudinal groove or recess F designed to receive the. lower portion of mem i bet F The parts of said screw are also held together by means of a pin Fflfwhich passes through coincident openings F inthe said jaws and the members of said screw. The

upper. portion F of member F receives the tension-enu't F the latter engaging the screwthread F The spring-tongue F presses against the interior of the. slot F and serves tdkeelp the. key F in, contact with the inner peripheryof the nut F which is constructed with a. series of recesses to act as stops for the purpose of locking the tension. When itis'desiired to alter; the tension, the head F is pressed to the center of the aperture in the The dotted line;

nut F thusreleasing the key- F from contact with the aforesaid stops and allowing the nut to be revolved as desired. The Whole of these parts constituting the tension appliance are shown in position in Figs. 6 and 7.

M is a beveled gear-wheel.

' N is a crank-pin which may be provided with a roller for'the purpose of reducing the friction.-- I

M is an aperture in wheel M, through i which spindle 0 passes and on which the said I gear-wheel revolves. ularly Fig. 5, thepointsof the lower blade A An elongated beveled pinion-wheel Pjs mounted on a flexible shaft and arrangedto engage the gear-wheel M. A portion of the body of the beveled wheel P is cut away, as shown, for purpose of forming a balariceweightor fly-wheel.

Q is a connecting-rod pivoted to pinion- -wheel P by pin P R is a. bearing in which one end of pinionwheel P revolves, forming a collar within the handle H, as hereinafter described.

The parts of the machine areso constructed and adjusted that the teeth of the movable blade B pass over those of the fixed blade A sufficiently far to allow of the wool to inter-- more tooth. Fig. 5 showsthe movable blade in the position taken up about-the middle of its stroke-r'. 6., with its teeth lying opposite the interstices of the teeth of the fixed blade.

Fig. 1 shows, approxi m atel-y, the position when the movable blade has reached the end of ,its stroke toward the right-'-thatis, when the teeth of the movable blade overlap those of the under, excepting only that on the extreme left. When the movable blade reaches the end of its stroke toward the. left, the teeth will again overlap, but this time the'tooth on the extreme right" of the lower bladewill be uncovered. It will thus be seen that every-tooth of bot-hblades cuts on both sides,-(excepting those on the extreme right and left of the lower blade.) Consequently the number of revolutions necessary to. efiectively operate this machine is much less than in. those hitherto in use which have onlyione cuttingblade.

It will be seen from the-foregoing that my machine differs not only in construction, but in the essential principle of movement, from all those now in use,.as in place of one, blade moving on a comb at an enormo-i'is velocity and chewing the wool the. principle on which my machine works is a comparatively-slow movement, by which the wool is out. between two sharp edges exactly as. if shorn by a 'pair of'shears or scissors.
